China's Tianwen-2 spacecraft has captured the first-ever close-up image of Earth's rare "minimoon", Kamoʻoalewa, providing scientists with an unprecedented view of the mysterious near-Earth object. The image was taken after the spacecraft travelled nearly one billion kilometres during a 13-month journey from Earth. Launched on May 29, 2025, by the China National Space Administration (CNSA), Tianwen-2 is China's first asteroid sample-return mission, designed to study a small celestial body in detail and bring material back to Earth for scientific analysis.

The spacecraft first detected Kamoʻoalewa on June 6 and gradually approached the asteroid over the following weeks. By July 2, Tianwen-2 had moved within approximately 20 kilometres of the object, allowing its instruments to capture detailed images of its uneven shape and rocky surface. The close-up observations have given researchers their first direct look at the asteroid's physical features, helping them better understand its composition, structure and possible origins.

Despite its popular nickname as a "minimoon", Kamoʻoalewa is not Earth's second moon. Scientists classify it as a quasi-satellite, a rare type of asteroid that travels around the Sun while remaining gravitationally connected to Earth. Its unusual orbit makes it appear as though it circles our planet, although it does not directly orbit Earth. Estimated to measure between 40 and 100 metres in width, Kamoʻoalewa is among the smallest asteroids ever approached by a spacecraft and is one of only a few known Earth quasi-satellites.

The Tianwen-2 mission aims to study the asteroid's surface, identify a suitable landing location and collect samples that can later be returned to Earth for laboratory analysis. According to scientists, studying the material from Kamoʻoalewa could help answer important questions about the formation and evolution of near-Earth objects. Researchers are particularly interested in testing the possibility that the asteroid may be a fragment of Earth's Moon, ejected into space following an ancient impact event.

Scientists believe the samples collected by Tianwen-2 could provide valuable insights into how quasi-satellites form, how they maintain their unusual orbits and how they evolve over millions of years. The mission is also expected to improve understanding of objects that remain close to Earth and could contribute to future planetary science research. As observations continue, Kamoʻoalewa may offer a rare window into the history of both Earth and the wider solar system.
